Gambler's Ruin Problem in Several Dimensions
Advances in Applied Mathematics, 2002 Consider symmetric simple random walk on \(\{0,1, \dots,N\} \times\{0,1, \dots,M\}\) with absorbing boundaries \(x=0\), \(x=N\), \(y=0\), \(y=M\). Let \(a(i,j)\) be the expected time to absorption when starting in \((i,j)\), satisfying \[ 4a(i,j)= 4+a(i+1,j) +a(i-1,j)+ a(i,j+1)+a(i,j-1), \quad 1\leq i\leq N-1,\;1\leq j\leq M-1,\tag{*} \] with boundary ...

A NOTE ON THE SEVERITY OF RUIN IN THE RENEWAL MODEL WITH CLAIMS OF DOMINATED VARIATION [PDF]
Bulletin of the Korean Mathematical Society, 2003 Summary: This paper investigates the tail asymptotic behavior of the severity of ruin (the deficit at ruin) in the renewal model. Under the assumption that the tail probability of the claim size is dominatedly varying a uniform asymptotic formula for the tail probability of the deficit at ruin is obtained.

GENERAL BOUNDS ON RUIN PROBABILITIES [PDF]
, 2019 In this paper we consider general bounds on ultimate ruin probabilities in a Poisson process when the claim severity distribution is not exponentially bounded. The bounds are derived using a variant of the Chebyshev inequality.

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?
FEBS Letters, EarlyView.This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.
